elf: Use _dl_catch_error from base namespace in dl-libc.c [BZ #27646]
dlerrror_run in elf/dl-libc.c needs to call GLRO (dl_catch_error) from the base namespace, just like the exported dlerror implementation. Fixes commit b2964eb1d9a6b8ab1250e8a881cf406182da5875 ("dlfcn: Failures after dlmopen should not terminate process [BZ #24772]"). Reviewed-by: Siddhesh Poyarekar <siddhesh@sourceware.org>
